SPECIFICATION forming part of Letters Patent N 0. 769,047, dated August 30, 1904. `Application filed February 4, 1904. Serial No. 191,991. (No model-.

To. all whom t may concern:

Beit known that we, GEORGE E. BAUMBER- GER and JOHN DIs'rELHoRsT, citizens of the United States, and residents of Burlington, in the county of'Des Moines and' State of Iowa, have made a certain new and useful Invention in Vehicle-Brakes; and we declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled inthe art to which it appertains to make and use the invention, reference -being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a perspective view ofthe invention as applied. Fig. 2 is a detail side view of the lever b broken away at the top.

The invention has relation to means for operatingthe brakes of vehicles; and it consists in the novel construction and combinations of' of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter t designates the side of a wagon 'body o r frame, and the brakelever; c, the upper rack; d, the lower rack, and e the connection-rod to the brake. The upper rack c has its teeth g projecting horizontally outward, and it is provided with a loop-guard z, extending alongside the rack, but at a sufficient distance therefrom to permit the brake-lever to be easily operatedin regard to its engagement with or disengagement from this rack. The lower rack d is lo-l cated parallel to the Lipper rack and'at a suficient distance therefrom to provide .for le`verage. This is a fulcrum-rack, and its lin'e of teeth or projections p between the fulcrumbearings 70 extends horizontally, while the teeth or projections are vertical.

The brake-lever has at its lower end portion av lo'op e, which engages the rack-bar of the lower rack, which is set out from the framebody in such wise that the loop of the lever.

extends around theysame, embracing it loosely. The loop e is long enough to allow the lever suiicient motion of reciprocation to permit the disengagement of the fulcrum-pin s, which is located in the loop near its upper end, from any one of the fulcrnm-bearings c. The lever is also provided with an elongated catch t, which extends alongits rear edge and is inclined inward or toward the teeth of the upper rack. with which it is designed to engage. This catch t is a little longer than the loop e, being so arranged that it can be brought into engagement with the upper rack'in any position of the lever. This elongated catch can be readily formed by twisting the metal bar in `making the lever. It isapparent that when there is any tension on the brake connection e the catch will be held in engagement with 4the upper rack. The fulcrum-pivot of the le- `upper rack then running as a fulcrum for making the change is readily moved to position labove the fulcrum-bearing desired and dropped, its fulcrum-pin engagingthe bearing.

Havingv described this invention, what We claim, and desire to secure by Letters Patent, 1sH

thereto, and a vertically-adjustable brake-lever having a terminal loop embracing said fulcrum-rack and forming a stop to limit upward movement of the lever, and a fulcrumpin at the upper end of said yloop and connecting loop and lever, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.
